This paper describes a practical image restoration method. Using PSF, which is deterioration information when the blurred image was taken, and the blurred image itself as an initial input image, this method estimates another image that the PSF is assumed to output and update the initial input image. This process of updating is repeated until the estimated output image is nearly the same as the actually taken blurred image. The updates on the input image are carried out while keeping updated pixels and surrounding area balanced, and therefore the restored image will have a natural appearance without ringing. This method enables us to achieve restored images without ringing even when PSF is inaccurate. Furthermore, using this method, restored images without ringing can be achieved through a blind process which uses only a blurred image.
